Chrysler's 3.2 liter V-6 engine was a new aluminum-block design based on the original 3.5 liter V6, launched in 1998 and dropped in 2002. Power was about the same as the original 3.5 engine, with a broader torque curve — an impressive feat, given the smaller displacement and the use of regular, rather than mid-grade, fuel.
The 3.2 V6 had a variable intake system, building on Chrysler’s work back in the 1950s and 60s; it varied the length of the intake manifold tubes to create a small, but useful, supercharging effect at different engine speeds.
Bob Sheaves set the order of the engine development and components (not actual production) as:
Willem Weertman’s Chrysler Engines suggests that the 2.7 was based directly off the 3.5 V6, but is really in its own engine family. In any case, all these engines were Chrysler designs, though some mistakenly attribute them to Mitsubishi.

All three engines had 24 valves (four per cylinder) and reduced emissions with at least one three-way catalytic converter, quad-heated oxygen sensors, and EGR.

The 3.2 used sequential multiple-port electronic fuel injection, with valves actuated by hydraulic center-privot roller rocker arms. The head was cast aluminum, on a semi-permanent mold cast aluminum block (using iron cylinder liners). Gas mileage in the Concorde was 19 city, 29 highway with a four speed automatic.
